Help::Auto-Download

When the slider is in the ON position clicking the download link will download the craft and open the download tab so show you more info

When the slider is in the OFF position clicking the download link will just open the download tab without downloading the craft

erm....why?
Once you've downloaded a craft the slider will automatically move to the OFF position, so you can then open the download tab without re-downloading the craft each time.
If you want to re-download the craft there will be a link in the download tab

It also acts as a visual que to remind you which craft you've already downloaded, if it's in the OFF position (red) you've already downloaded the craft.
As you are not logged in it will only remember what craft you've downloaded in this session.

You’ll get best results out of this airplane if you install V.O.I.D. so you’ll have an engine speed readout. Just like real life, a propeller has an optimum blade angle for every speed. Propeller speed too high means too much drag/pitch angle too low. Propeller speed to low also means too much drag but angle too high.

For anything with turboshaft engines, stock drag is too high. Use the F12 menu -> Physics tab -> Drag tab, set Global Drag Multiplier to minimum. It will fly with standard settings (top speed 71m/s) but it’s boring. I invented the stock turboprop/turboshaft engine and the previous golden age was during KSP 0.90. That’s my frame of reference.

When using V.O.I.D, switch off kerbal engineering calculations or you’ll get a massive performance hit.

If you want the ability to get 100% performance out of my turboshaft engines, go to your Physics.cfg in the KSP root folder, change line 89 which says maxAngularVelocity = 31.416. Set the value to 60 or higher. This engine will get damaged or fantastically explode at speeds higher than 51rad/s (487 RPM). Resolved in KSP 1.2.

This engine/propeller setup has an optimal speed between 48.5 - 49.9rad/s. It will provide best fuel economy and speed.

Cruise:

Keep the propeller running at peak efficiency (48.5 - 49.9 rad/s), switch off first stage blowers. This is better than reducing throttle, first of all FPS increases while the more efficient second stage provides better fuel economy.

Engine failure:

Set the propeller pitch to max to reduce drag and increase range while gliding.

Landing:

Set propeller pitch low (watch engine speed!) to increase drag. It’s the only airbrake it has and works fine.

The aircraft is very easy to fly at all speeds and all attitudes.
